Exploration Round-Up

So much exploration news rolls through the wires that it’s impossible to write posts about all of it, even a small fraction of it. So I tweet when I can, but 140 characters is not a lot of space to offer analysis or even useful links. So I am going to the occasional round-up here: a short, annotated, links page to developing stories. Think of it as a expeditionary snack: more calories than a tweet, less filling than a post.
